Name Class::Usul - A base class providing config, locking, logging, and l10n Version Describes Class::Usul version v0.50.$Rev: 1 $ Synopsis use Moo; extends q(Class::Usul); $self = Class::Usul->new( $attr ); Description These modules provide a set of base classes for Perl packages and applications that provide configuration file loading Class::Usul::Config, locking to single thread processes IPC::SRLock, logging Class::Usul::Log and localisation Class::Usul::L10N The class Class::Usul::Programs is a base class for command line interfaces Interprocess communication is handled by Class::Usul::IPC Class::Usul::File makes the functionality of File::DataClass available The Module::Build subclass Class::Usul::Build adds methods for the management and deployment of applications Configuration and Environment Defines the following attributes; config The config attribute should be a hash ref that may define key/value pairs that provide filesystem paths for the temporary directory etc. config_class Defaults to Class::Usul::Config and is of type LoadableClass. An instance of this class is loaded and instantiated using the hash ref in the config attribute. It provides accessor methods with symbol inflation and smart defaults. Add configuration attributes by subclassing the default debug Defaults to false encoding Decode input and encode output. Defaults to UTF-8 Defines an instance of IPC::SRLock Defines the application context log. Defaults to a Log::Handler object Subroutines/Methods dumper $self->dumper( $some_var ); Use Data::Printer to dump arguments for development purposes _build__lock Defines the lock object. This instantiates on first use An IPC::SRLock object which is used to single thread the application where required. This is a singleton object. Provides defaults for and returns a new IPC::SRLock object. The keys of the $self->config->lock_attributes hash are: debug Debug status. Defaults to $self->debug log Logging object. Defaults to $self->log tempdir Directory used to store the lock file and lock table if the fcntl backend is used. Defaults to $self->config->tempdir Diagnostics Setting the debug attribute to true causes messages to be logged at the debug level Dependencies Class::Usul::Constants Class::Usul::Functions Class::Usul::L10N Class::Usul::Log IPC::SRLock Moo Incompatibilities There are no known incompatibilities in this module Bugs and Limitations There are no known bugs in this module.
